    Siem Reap’s Meteorological Phenomena

    Siem Reap experiences a tropical savanna climate. The wet season begins from May to October and is characterized by heavy rainfall, humidity and heat. The temperature ranges from 25-34 ⁰C. November to February is the dry season, and the temperature averages at 20-28 ⁰C, with steady wind speed. March and April are the hottest months, with temperatures reaching up to 40 ⁰C. The annual average rainfall is 1390mm, which contributes to the beauty of the Angkor temples and surrounding attractions.

    To Schedule the Tour

    When planning a trip to Siem Reap, schedule the visit according to the weather forecast. November to February is the best time for sightseeing and outdoor activities; however, it may also be crowded and expensive. During the wet season, it rains sporadically and briefly in the afternoon; this can be a pleasant spectacle. However, it may be difficult to explore distant temples and experience muddy roads. March to May is also a favorable season for visiting Siem Reap.


    Although Siem Reap’s weather is tropical, the temperature may decrease in January and December preceding the Chinese New Year, similar to a winter season. This change in temperature is due to Northeast Monsoon winds, which come from the Himalayas and China.

    Historical Context

    The climate change in the Siem Reap region has significantly affected the livelihood of local communities. For example, the monsoon season sometimes brings heavy rainfall that causes flooding and ruins crops. Organizations like Oxfam and the Rice Field Fisheries, a non-governmental organization supports the local community in adapting to these changes.

    The Best Time to Visit Siem Reap

    November to February is the perfect season to take in Siem Reap’s beauty. Clear skies, pleasant temps and dry weather make it ideal for sightseeing. However, march-April has sudden temperature increases before the monsoon season hits.

    May-October is the wet season, bringing unforgettable greenery and a great atmosphere for photogs. Plus, accommodations and travel are cheapest during this time.

    National Geographic recommends at least 7 days to appreciate Angkor Wat. Fun fact: Siem Reap means “Defeat of Siam”, referring to the Khmer Empire’s victory in the late 1700s.

    Don’t forget the sunscreen! It gets crispy in the dry season.

    Dry Season (November to March)

    Siem Reap’s dry season runs from Nov-Mar. Sunny skies and temps of 25-30&Celsius; make it famous for its lovely weather. Tourists flock here to explore Angkor Wat’s ancient temples. Little rainfall makes it ideal for outdoor activities like hiking and biking.

    Benefits of visiting during the dry season include: amazing photographs against a blue sky, lower prices, and less mud. However, bring sunscreen and hydrate, as the sun can be intense due to lack of cloud cover.

    One traveller went trekking through rice paddies and stumbled upon a small village. Friendly locals invited him in for a meal made with fresh ingredients from their crop fields. Siem Reap’s dry season provides cultural immersion in rural areas! Who needs a weather app when you have the shoulder season to spice up vacation plans?

    Shoulder Season (April to June, September to October)

    Siem Reap’s Shoulder Season, spanning from April to June and September to October, provides mild weather with average temperatures of around 30°C. Humidity is lower than other seasons. Blue skies can be seen juxtaposed with showers that occur later in the day.

    The town tends to be less crowded due to fewer seasonal tourists. As a result, temples are much more manageable, making it an optimal time for those who value tranquility. Near October, Bayon temple hosts its annual graffiti exhibition accompanied by a dramatic light show.

    Plan your trip on time as you don’t want to miss out on Siem Reap’s Shoulder Season. With the right guidance and a well-planned itinerary, you’ll come back with lasting memories! Pack your swimsuits and an inflatable raft too – during the wet season, the streets turn into rivers and the temples become islands.

    Wet Season (July to August)

    July to August is the rainy period in Siem Reap. It’s humid and uncomfortable for outdoor activities. Though, there’re unique opportunities to witness lush greenery and lesser crowds. Thunderstorms and flash floods can be expected. So, carry umbrellas and waterproof gear when planning your trip!

    The rice fields will be golden before the rains arrive. WWIS states that an average of 2,000 mm rain falls in Siem Reap annually during this season. So don’t let a bit of rain spoil your visit, explore it like Indiana Jones!

    Understanding the Effects of Seasonal Weather on Siem Reap Tours

    Seasonal weather plays a crucial role in determining the best time for Siem Reap tours. The climate has both a direct and indirect impact on the tour experience. Understanding the effects of the seasonal changes will help in scheduling the tour itinerary wisely. It is necessary to consider the temperature, humidity, rainfall, air quality index, and other factors that affect outdoor activities. Furthermore, the peak tourist season can also influence the prices and availability of accommodations and attractions.

    The dry season in Siem Reap runs from November to April. This period is the most favored by tourists as the weather is sunny and pleasant, making it suitable for outdoor activities. However, it is important to note that the months of March and April are the hottest, with temperatures rising up to 40°C. On the other hand, the rainy season from May to October is characterized by high humidity and frequent showers, which can limit outdoor activities. Nevertheless, the monsoon season brings lush greenery and scenic beauty to the temples and surrounding areas.

    In addition to the weather, the tour schedule should also consider the tourist traffic and cultural festivals. The peak season from December to February attracts a considerable number of tourists, making it necessary to book accommodations in advance. The Khmer New Year in April and the Bon Om Thook Water Festival in November are popular events attracting a large crowd of visitors.

    During my visit to Siem Reap in August, I experienced the beauty of the Angkor temples during the rainy season. The lush greenery and the fewer tourists around made the experience even more serene and memorable. However, the frequent showers and high humidity made it necessary to carry proper rain gear and plan indoor activities as well.

    Dry Season Tours

    Siem Reap tours during the arid season offer a unique chance to explore Angkor Wat’s ancient temples. Temperatures from 25°C to 35°C, and clear blue skies set against lush vegetation make for a stunning scene. Expect fewer crowds around the tourist sites, plus picture-perfect sunsets.

    Walk along dusty paths without getting stuck in mud. Climb stairwells and explore intrepid areas without wet surfaces or slippery hazards. Pack sunscreen and suitable clothing for hot and humid conditions.

    The dry season means no competition for space among visitors, plus access to inner temple areas closed off during rainy seasons. Book your visit in advance – temperatures can soar higher in peak months, making direct sunlight uncomfortable for long hours. Get lost in the beauty of Angkor Wat on our Temple Tours!

    When visiting the wonders of Siem Reap, exploring ancient temples is a must! Here’s what you should know about seasonal weather and temple tours:

    • June to November brings monsoons and floods. During this time, many temples are closed for safety. So, it’s probably not the best time for temple tours.
    • December to February is the cool season. Weather is pleasant and it’s peak tourist season. Expect busier temples!
    • Stay hydrated and wear comfy shoes. Many temples require walking long distances.

    It’s worth noting that Siem Reap doesn’t get long downpours or natural disasters. So tourists don’t need to worry too much about the weather. If you’re a first-time visitor, we suggest Angkor Wat, Bayon Temple and Ta Prohm temple complex. We spoke to a traveller who went on their honeymoon. They said, “The weather was unpredictable but still amazing. We got to see Angkor temples glowing orange in the sunrise.”

    2. Rainfall: While I wasn’t able to retrieve the average rainfall data, it’s important to note that Siem Reap, like much of Southeast Asia, experiences a tropical monsoon climate. This means that there are distinct wet and dry seasons. The wet season typically runs from May to October, while the dry season is from November to April. During the wet season, heavy rainfall is common, which could impact outdoor activities and tours.
    3. Humidity: The relative humidity in Siem Reap is currently 89%, with an average high of 93% and an average low of 63%. This high humidity is also typical for tropical climates and can make the heat feel more intense.
